What are nerve conduction studies?

Measure speed: Nerve conduction studies measure the speed of the nerve impulse signal traveling the course of a particular nerve. These studies are used to indicate damage to a nerve. They are frequently used to diagnose carpal tunnel syndrome and other neuropathies.

Test nerve function: They are a way to test the function of nerves in the body, looking for focal (like carpal tunnel) or generalized (like diabetic neuropathy) problems. They are performed by stimulating the nerve electrically (which feels like touching a doorknob after shuffling your feet on a carpet on a dry day), and recording the response. They are uncomfortable, but very helpful in clarifying a diagnosis.
